Question Tires for Bracket Racing Events

So, I came across this thread and thinking if the radials would be better than the bias for bracket events.

I need to look for tires 14 x 32 x 15 and wondering if I just pull the trigger on new radials??

Mickey Thompson makes a 32x14r15 Pro Bracket Radial. In my experience the Pro Bracket Radial is about .08-.10 faster on my car than a biased ply and a lot more stable on the top end.

How much power and what type of car?

I wish MT would make a 32 x 11 x 15 tire. Would be nice to get a radial an inch taller than my 30s with 10.5 tread.

You're lucky you have large wheel wells. I am squeezing a 28x9 under the 65. Wish they made a 29.5x9

1969 Firebird with a RA V 413CI in a back half chassis.
I've yet to dyno it or put the car on a scale, but I'm figuring about 625 to 700 Hp.

I would think you would pick up at that power level. Will definitely drive better on the top end.

A pic on the car. They have a smaller diameter then my Hoosier QTP 28x11.5-15 and a 1/2" less section width using an 8" rim.
